BARREL-MACHINE.

SPECIFICATION forming part ofLetters Patent No. 224,587, dated February 117, 1880.

Application filed December 18, 1879.

. with the accompanying drawings, is a specification.

In the drawings, Figure 1 is a top or plan view of a barrel-machine embodying my invention; Fig. 2, a vertical section in the plane of the line a: m; Fig. 3, a rear view of the guides and trimmers detached, and Fig. 4 a top or plan view of the same.

Like letters of reference indicate like parts.

My invention relates to that class of barrelmaking machines adapted to make barrels consisting'of veneers wound upon an expansible and contractible cylinder, and bound by means of hoops. Heretofore machines of this class have been provided with guides for the purpose of holding inplace the strips forming the hoops while the latter were being applied.

My present invention relates only to these guides, and my object is to so construct them that they will perform the function of trimming the edges of the hoop-strips, as well as the function of guides.

To this end my invention consists in constructingthe guides substantially in the manner hereinafter set forth.

1n the drawings, A represents the frame of a barrel-making machine of the class hereinbefore referred to, and B is the cylinder. 0 G are the guides, and D is a presser-roller, cut as shown at a. a, to receive the hoops. E is the veneer forming the body of the barrel, and F F arethe hoop-strips.

My invention, as before stated, relates wholly to the guides O G, and in order to cause them to perform the function of trimmers, as well as of guides, with advantage, I make the rear edges of the vertical parts of the guides sharp or knife-like, so that these sharp edges, which are arranged for contact with the edges of the strips F F as the latter are being wound upon the veneer upon the cylinder, will trim off the g edges of the said strips where they are unguides, and 0 c are the sharp or knifelike edges. These edges maybe made sharp either by grooving them, as shown at c c, or by beveling them, or in any well-known and suitable way, and I do not therefore here intend to restrict myself to the grooves 0 c. g

It will be perceived from the foregoing description, and from reference to the drawings, especially to Fig. 1, where the relative positions of all the parts are clearly shown, that the guides O C will also perform the function of trimmers.

. Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination, with the cylinder and frame of a barrel-makin g machine,of the hoopguides and trimmers O 0, having guide portions 0 O, with sharp or knife-like edges 0 c, substantially as and for the purposes specified.
